Product details
Overview
AD9608BCPZ-105 from Analog Devices is a dual-channel, 10-bit, 105 MSPS analog-to-digital converter operating from a single 1.8 V analog supply, featuring differential analog inputs with 650 MHz bandwidth, on-chip voltage reference, and support for 1.8 V CMOS or LVDS digital outputs. It delivers 61.7 dBFS SNR at 70 MHz input and −85 dBc worst other spur, targeting IF sampling in communications infrastructure.
For engineers reviewing the AD9608BCPZ-105 datasheet, AD9608BCPZ-105 pinout, AD9608BCPZ-105 application, or AD9608BCPZ-105 equivalent, this page provides verified specifications, package mapping to 64-lead LFCSP, functional pin roles, real-world use cases in diversity radio and ultrasound systems, and two validated alternative ADCs with documented technical differences.
Technical Context
The AD9608BCPZ-105 employs a multistage differential pipeline architecture with output error correction logic to guarantee 10-bit accuracy and no missing codes across −40°C to +85°C. Its sample-and-hold circuit supports IF sampling up to 200 MHz while maintaining 61.3 dBFS minimum SNR and 75 dBc minimum SFDR over full temperature range.
Dual-channel operation is synchronized via shared differential clock (CLK+/CLK−) with optional duty cycle stabilizer (DCS), and digital outputs are configurable as offset binary, Gray code, or twos complement. The device supports integer 1-to-8 clock division, data multiplexing, and programmable DCO/data alignment for timing-critical receiver designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Resolution | 10-bit - guarantees monotonic transfer function and no missing codes over full industrial temperature range. |
| Sampling Rate | 105 MSPS - fixed maximum conversion rate for AD9608BCPZ-105 variant, enabling Nyquist-limited IF digitization up to 52.5 MHz. |
| SNR @ 70 MHz | 61.7 dBFS - measured with −1.0 dBFS differential sine input; determines dynamic range for wideband signal capture. |
| SFDR @ 70 MHz | 85 dBc - specifies spurious-free performance critical for multi-carrier communication systems. |
| Analog Input Bandwidth | 650 MHz - supports high-frequency IF sampling without external anti-alias filtering below 200 MHz. |

| Differential Nonlinearity | ±0.13 LSB (typ) - ensures linearity fidelity for precision measurement applications like portable medical imaging. |
| Input Voltage Range | 2 V p-p differential - matches standard transformer-coupled or balun-based RF front-end interfaces. |
Pinout & Package
AD9608BCPZ-105 is housed in a 64-lead, 9 mm × 9 mm RoHS-compliant LFCSP with exposed thermal pad that must be soldered to PCB ground plane for proper thermal and electrical performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

FAQ
What is the maximum analog input frequency supported by AD9608BCPZ-105?
The AD9608BCPZ-105 supports analog input frequencies up to 200 MHz in IF sampling applications, enabled by its 650 MHz analog input bandwidth and patented sample-and-hold circuit. This allows direct digitization of first or second IF stages without downconversion, and the device maintains 61.3 dBFS SNR and 75 dBc SFDR across the full 200 MHz band.
Does AD9608BCPZ-105 support both CMOS and LVDS output interfaces?
Yes, AD9608BCPZ-105 supports both 1.8 V CMOS and 1.8 V LVDS digital outputs, selectable via SPI register or hardware pin configuration. In CMOS mode, it delivers 10-bit parallel data per channel with DCO timing; in LVDS mode, it provides differential signaling with 290–400 mV VOD and ANSI-compliant common-mode voltage, reducing EMI and improving noise immunity.
What is the purpose of the SYNC pin on AD9608BCPZ-105?
The SYNC pin on AD9608BCPZ-105 provides deterministic synchronization across multiple ADCs in multi-channel systems. When asserted, it resets internal pipeline stages and aligns sampling phases across devices sharing the same clock source, ensuring sub-cycle timing coherence essential for phased-array radar or MIMO communications.
How does the duty cycle stabilizer (DCS) function in AD9608BCPZ-105?
The duty cycle stabilizer (DCS) in AD9608BCPZ-105 compensates for wide variations in input clock duty cycle without degrading SNR or SFDR performance. Enabled via SPI or hardware pin, DCS internally generates a symmetrical clock waveform from asymmetric inputs, maintaining aperture uncertainty below 0.137 ps rms even with 30%–70% duty cycle distortion.
Is AD9608BCPZ-105 pin-compatible with other Analog Devices ADCs?
Yes, AD9608BCPZ-105 is pin-compatible with the AD9650, AD9269, AD9268, AD9258, AD9648, AD9628, AD9231, and AD9204 families in the same 64-lead LFCSP package. This enables seamless migration between 10-bit and 16-bit converters sampling from 20 MSPS to 125 MSPS without PCB redesign.
